Getting clean output from Extreme switch CLI using Python

[Marvel_King]

I am writing a python script to run some show commands on Extreme switches and storing output in a variable. I am able to accomplish that but the output is not as I would like. I am seeing the command and also switch name in my output but I would like to just see the result of my show command and nothing else.

This is what I am seeing:

print "ISC Port is: ", ISC

ISC Port is: sh vlan ISC | i Tag:
Tag: 1:1g
Ext-SW1.com.5 #

This is what I would like to see:

ISC Port is: Tag: 1:1g

Here is my code where I am reading output:

ISC = "sh vlan ISC | i Tag:"

tn.write(ISC + "\n")
idx, obj, output = tn.expect(["\.\r\n\r\*"], int(timeout))
print "ISC Port is: ", outputHow do I get rid of device name and my commands from output to show only output. I played around with "read_until" but can't seem to get it cleaned up. Example:

tn.write(ISC + "\n")
tn.read_until(".2 #")
idx, obj, output = tn.expect(["\.\r\n\r\*"], int(timeout))
print "ISC Port is: ", outputAny help will be appropriated.

No, we are running 15.x.

As Dave mentionned, if you are running 21 or later, you really should consider JSONRPC.

If the switch is running EXOS 21.x or later, you could use JSONRPC instead of screen scraping the telnet display. An example script is here: https://github.com/extremenetworks/ExtremeScripting/tree/master/EXOS/Python/jsoncli
